Install Updates could not successfully download

Can't see the actual error messages there, it looks like the log may be truncated.
You can manually re-run the update process and record the process to text files.
If you post the resulting text files back here it might show what is happening.

To do this, open a terminal by pressing 'Ctrl' 'Alt' and 'T' keys together.
In the terminal window, type or paste in

Code:

sudo apt-get update | tee ~/"$(date +"%Y_%m_%d_%T")-apt-get-update.txt"

followed by return/enter.  Enter your password if asked.
Then type or paste in

Code:

sudo apt-get upgrade | tee ~/"$(date +"%Y_%m_%d_%T")-apt-get-upgrade.txt"

followed by return/enter. Press 'y' at the prompt 'Do you want to continue?'.

Running those commands should carry out the update/upgrade process and create two files called apt-get-update.txt and apt-get-upgrade.txt in your home directory.
The filenames will be prefixed with date and time information.
You can watch the screen or open the files when done to confirm they have captured the error information.

Post back and attach the files.

Note that 'apt-get' may not attempt all the possible upgrades.
If the errors aren't in the two apt-get files then you may need to use the similar apt commands.

Code:

sudo apt update | tee ~/"$(date +"%Y_%m_%d_%T")-apt-update.txt"

Code:

sudo apt upgrade | tee ~/"$(date +"%Y_%m_%d_%T")-apt-upgrade.txt"

Again, you may need to enter your password and any answer confirmations.
